Archaeologists have unearth a series of protective walls built around the Sphinx at Giza in Egypt. According to ancient texts, the walls were built to protected the sculpture from blowing sands after Pharoah Thutmose IV (1400-1390 BCE) had a dream in which the Sphinx complained blowing sand was choking it. The Sphinx is believed to have been built more than 1100 years earlier than the protective walls.
